Chuck, you`re wecome anytime;we did try starting one of the -4s,but whilst they would turn and `chuff,fuel ran outwhen the pumps went on. A couple of yrs ago it ran for a while ,but the system was jury-rigged from a tank in the fuselage with pipes out along the wing to the engines,bypassing the mains.Nothing since. Other stuff you can find on the NW Thread on `Key publishing /Flypast site`.
